The configuration of the present embodiment is also effective when adding future AI new functions, biological signal processing functions, and the like.

For example, in the case where the wireless earphone 1 has an AI function, if the cradle 50 is provided with a speaker (not shown), the cradle 50 can be used as an AI speaker. An AI speaker is a speaker that can use an AI assistant that supports interactive voice operation, and has recently been widely used in various applications such as music viewing via the Internet, use of search services, shopping, etc. . According to this configuration, not only the wearer of the wireless earphone 1 but also surrounding friends and family can listen to the output from the AI function of the wireless earphone 1 (for example, information provision from AI, advice, music, etc.) it can. In addition, since the cradle 50 can be carried, there is an advantage that the AI function of the wireless earphone 1 can be utilized at various places such as outdoors or in a car unlike the stationary AI speaker.

Further, in this case, if not only the speaker but also the microphone (not shown) is provided in the cradle 50, a user other than the user of the wireless earphone 1 can also give an audio instruction to the AI function via the microphone of the cradle 50. It becomes possible.

In addition, since the wireless earphone 1 is not equipped with a display, conventionally, when visually checking data stored in the wireless earphone 1 or changing it while looking at the setting contents, conventionally, a smart watch, a smartphone, etc. Display terminals were sometimes required. On the other hand, according to the sound reproduction apparatus according to the present embodiment, such a display terminal is unnecessary, so that cooperation between devices can be simplified, and the economic burden on the user can be reduced.

The operation of the wireless earphone 1 using the touch panel 51 as a GUI is also possible in a state where the wireless earphone 1 is attached to the ear without being accommodated in the cradle 50. In this case, the wireless earphone 1 and the cradle 50 communicate via Bluetooth.

Second Embodiment
The second embodiment of the present invention will be described below. In addition, about the structure which has the same function as the structure demonstrated in 1st Embodiment, the same referential mark is attached and the detailed description is abbreviate | omitted. The same applies to each embodiment described later.

FIG. 4 and FIG. 5 show an example of display on the touch panel 51 of the cradle 50 of the second embodiment. The left figure is a menu screen 60 of fitness log data, and the right figure is a graph display screen 61 for plotting the log data selected in the menu and displaying it.

In the present embodiment, the sensor unit 7 includes an acceleration sensor, a gyro sensor, a heart rate sensor, and the like. The data acquired by the sensor unit 7 is taken in and processed by the sensor signal processing unit 24 of the processor 11 and accumulated in the memory unit 22. As a result, when the user wears the wireless earphone 1 and exercises, data on exercise (for example, walking or running distance, number of steps, speed, calorie consumption, heart rate, etc.) can be stored in the memory unit 22.

In the present embodiment, when the wireless earphone 1 is stored in the cradle 50, data stored in the memory unit 22 is transferred to the cradle 50 via the connector 3 and the log data processing unit 56 receives the data. The log data processing unit 56 processes the data transferred from the memory unit 22 of the wireless earphone 1 to generate a graph or the like and displays it on the touch panel 51.

The sensor unit 7 and the memory unit 22 may be provided only in one or both of the left ear wireless earphone 1a and the right ear wireless earphone 1b.

When the sensor unit 7 and the memory unit 22 are provided in both the left ear wireless earphone 1a and the right ear wireless earphone 1b, sensor data is acquired from each of the left ear and the right ear and stored in the memory unit 22. . Also, in this case, when the wireless earphone 1 is stored in the cradle 50, the log data processing unit of the cradle 50 is obtained from the memory unit 22 of the left-ear wireless earphone 1a and the memory unit 22 of the right-ear wireless earphone 1b. Data is sent to 56. As a result, the log data processing unit 56 can separately display the processing results of the log data of the left and right ears, and can monitor changes in physical function and balance. Of course, if it is resistant to always wear both of the wireless earphones, the same effect can be expected even if one of the left and right wireless earphones is worn.

In the example of FIG. 4, when the user selects the distance (distance) by the touch operation on the touch panel 51 as shown on the left, the display on the touch panel 51 is processed by the log data processing unit 56 as shown on the right.

Further, in the example shown in FIG. 5, as shown in the left figure, when the user selects the heart rate (Heart Rate), as shown in the right figure, the display of the touch panel 51 is switched to display a heart rate waveform. The current heart rate, the maximum heart rate within a predetermined period, and the average heart rate are displayed as text next to the heart rate waveform. Since the wireless earphone 1 and the cradle 50 can be connected by Bluetooth even while the user is wearing the wireless earphone 1, the output of the sensor signal processing unit 24 can be displayed in real time. For example, even while exercising with yoga while listening to music with the wireless earphone 1, it is possible to grasp the current condition of one's own body on the screen displayed on the touch panel 51. Although biological data detected from the left ear or the right ear is displayed in FIG. 5, it is also possible to compare and display detection data of both the left ear and the right ear. Changes in body function and balance can be monitored by comparing left and right detection data.

As a method of detecting the heart rate, in addition to the heart rate sensor, a microphone capable of detecting the vibration of the air generated by the vibration of the skin or tympanic membrane portion accompanying the pulsation of the blood vessel is used to close the microphone and the vibration source. It is also possible to use a measuring device that detects the pulsatility signal.

FIG. 6 is a block diagram of the wireless earphone and cradle of the second embodiment. An example of the function of the block diagram shown in FIG. 6 will be described. When the user makes a question by voice as “Today's health condition?”, The microphone 6 detects voice, and after the processor 11 recognizes voice, the past data accumulated in the memory unit 22 and the log data processing unit 56 of the cradle 50 The speaker transmits a message to the user of the calculation result obtained by comparing with the real time data detected from the sensor unit 7. For example, you can give appropriate advice by voice saying "Let's relax a little more". Further, when the user is running long distances, it is possible to transmit the distance to the destination, the lap time, the physical condition and the like by voice as a result of calculating the position information and the traveling distance by the GPS 9.

As described above, according to the sound reproduction device of the present embodiment, it is possible to display the analysis result of motion information and biological information acquired by the sensor of the wireless earphone 1 on the touch panel 51 of the cradle 50 during charging or in real time. it can.
